There is only one word that can describe this piece: Amazing.
I use this as the Lockscreen/Springboard wallpaper on my iPod Touch If only there was a desktop wallpaper of this, I would just gaze at my monitor for hours, there's something about it that just captures you.
And yeah, many have asked for some wallpaper-versions of some of these older space-pics, some I was able to deliver but some not, since I lost a small part of my files ages ago when one hard-drive crashed.
Unlucky. I hate hard-drive failure, and sorry to hear about that. I had it happen to me once; i had a 400GB external hard-drive that I put EVERYTHING on, such as programs and music etc, to keep my main c:/ drive with as much space as possible. One day it just decided to... stop.
